ADDING-MACHINE.

Specification of Letters Batent.

Application filedjuly 14, 1911.

To all whom it m my concern lie it known that I, LOUIS BABINI, a citiyrn of the United States, residing at Brooklyn, 1n the county of Kings and State of New York, have invented certain new and 'useful Improvements in Adding- Machines, of which the following is a full, clear, and

exact description, reference being had to the accompanying drawings, forming a part of to adding machines mechanism by the action of the same levers,

and its principal object is to provide an adding machine of a simple design and substantial construction, adapted to be manufac-v tured and sold at. a low figure, and to perform in a reliable way all the services usually required of an adding machine.

A further object of this invention is to provide a novel and simplified mechanism for printing the different figures in a proper order on strip of paper, while at the same time said figures are automatically added by the adding or registering mechanism.

With these and other objects in yiew, as will more fully appear as the description proceeds, this invention consists in certain constructions and arrangements of parts as will be hereinafter described and claimed in the appended claims.

Referring to the drawings, Figure 1 is a side sectional view in elevation of my improved machinc, showing the operation of the adding'mechanism; Fig. 2 is a side view in elevation of the same, with some parts of the printing mechanism removed, and some sectioned; Fig. 3 is a side view in elevation of the machine, showing all parts of the printing mechanism in place; Fig. 1 is a detail pla view of certain parts printing mechanism; Fig. 5 is a detail view on an enlarged scale, and sectioned, of an arrangement for setting all the counting wheels at the starting point; Fig. (l is a rear view in elevation, partly broken away, of the machine; Fig. 7 is a front view in elevation of the same; and Fig. 8 is a plan view of the same.

My-improved machine consists essentially of the .of three parts; one stationary, or body proper of the n'iachine, embodying the operating parts; one movable, or carriage, in which is mounted the adding mechanism; and a device attached to the side of the body, for printing on a strip of paper the different, addcnda, which are at the same time summed up in a general total by the adding mechanism. The stationary part comprises .a case 1, provided with a fulcrum rod 2, on which areloosely mounted nine levers 3, and provided with a fulcrum rod 5 on. which are loosely mounted two levers 6, 7. Levers are provided with touches 4 numbered from 1, to 9, and levers 6, 7, are providedwith touches 1, corresponding respectively to the numeral 0 and tothe spacing device for allowing the escapement of the carriage of one column space to the 'left. A rod 8 acts as a fulcriun for nine geared segn' ents 9, connected by links 10 to levers 3, and operated by the same; springs 11, attached to a rod 12. oppose the depressing of levers 3, and will return the same to their original position, shown in the drawings (Fig. 1). On the fulcrum Sare also mounted, one at each-side of case 1, and internally to the same, two crank levers having an upper arm 18 and alower arm 14. The two arms 13 are connected by a rib 15, and the two arms 14 are connected by a rib 16. The lever G has its free end abutting against the lower side of saidrib 16, as shownin Fig. 1.

A geared drum 18 is mounted on a shaft 19 running the entire length of case 1, and projecting outside at the left side of the sameg and said drum 18 is adapted to come inmesh with any of-the segi'nents 9, upon these being operated by the corresponding levers 3. Said segments 5) have a portion 5) provided with teeth. and a toothless portion 9, which in position of rest, as shown in Fig. lis opposite geared drum 18, allowing the free movement of thesame. A toothed wheel 20, from which a portion of its teeth have been removed, and which in the preferred embodiment of my invention is shown as having twelve teeth with two teeth missing, is fixed on drum 18in such a manner that in the position of rest, the free space left by, the missing teeth will clear the train of adding wheels 21, which is mounted on a shaft 22 in carriage 23, thereby permitting the free longitudinal mdtion of saidcarriage.

24 is a lever loosely niounted on a pivot 25 on tlieright or on the left side of case 1, and is provided with two notches, ,26, 27, a fingler 28 at one end, and a stop 29 abutting aga'nst the inside surface otcase 1, at the ather. Drum 18 is also provided with a finger 30. In the position shown in the drawings, notch 26 engages rib 15 connecting arms 13 (Fig. 1),.

Upon one of the levers 3 being depressed with the finger, the corresponding link 10 will pull arm 31 of the'eorresponding geared segment 9, causing *the same to revolve around its fulcrum 8 and to come in mesh with drum 18, rotating the same an angle proportional to the number of teeth in the segment which have come in mesh. At the end of the stroke, free end 32 of the segment, will strike against rib 15, swingin arms 13 toward the rear, until lever 24 will fall on account of its weight, and notch 27 engage rib 15, preventing the same trom goingback to its previous position. Upon releasing the lever 3, spring 11 will return it to its former position, causing a reverse movement of segment 9 and drum 18 to take place. At the end of this return stroke, fin ger 30 of drum 18 striking against finger 28 of lever 24, will swing said lever so that rib- 15 will be disengaged, and the weight of arms 14 will cause arms 13 to return to the pcsition'shown in the drawings, rib 15 engaging again iiotch 26. r

The carriage, 23, is slidabl y mounted on a rod 33, attached to the rear part of case 1 by means of upright 34. Said carriage is pulled toward the left side of the machine by a tape 35, attached to its bottom, and winding itself upon a drum of a spring motor of ordinary design, 36. The motion of the carriage is controlled by a rack .37 swinging on a. shaft 38, said rack being normally held in its forward position shown in the drawings, against stop 39, by the action of a spring 40 pulling its arm 41, or in any othersuitable manner (Fig. 1). Said rack 37 is provided with a number of teeth 42, one of which is normally abutting against a stop 43 projecting through thebottom of the carriage. Another stop 44 projects through the same, at the rear of stop 43, and at its left side, looking from the rear of the machine, as in Fig. 6. lln this same figure, between the two stops, is seen a free space 45, sufficient for the passage of one tooth 42 of the rack. Said stops 43, 44, (Fig. 1) are not fixed to the bottom of the carriage, but are attached to a spring 46 internally fixed to the same, and project through its bottom. Said spring 46 is attached in 47 to the front of the carriage 48, so that a pressure directed upward against the lower face of stops 43, 44, will raise thesame against the action of said spring. Rack 37 is provided with housings 49, through which project arms 52 of lever 50.'- This is a part of a column selecting device which may be built in con-- turn them tothe position shown in the drawing, until stops 59 will abut against the inside of case 1 (Fig. 1). Rack 37 is also provided with an arm 60, projecting above rib 16.

Each counting wheel 21 consists of a drum 21 in which are marked the numerals from' 0 to 9; of a toothed part 21", adapted to come in mesh with toothed wheel 20; and of a hub 21 of a smaller diameter, clearing the outside diameter of wheel 20, and cansing a gap 61 to be formed between one part 21 and one part 21 of the next counting wheel. One toothed part 21 is normally in front of wheel 20, so that upon this being revolved, it will drive part 21" and corresponding drum 21 for an angle corresponding to the number of teeth of the segment causing the rotation of drum 18 and wheel 20 (Figs. 1, 5, 7).

The operation of these different parts is as follows: Upon one of the levers3 being depressed, the corresponding segment 9 is swung around its fulcrum 8 in themanner described, causing the rotation of drum 18, and wheel 20, a numberof teeth proportional to the number of teeth in the segment coming in mesh with said drum. Wheel 20 will in its turn cause the rotation of the wheel 21 and corresponding numbered drum 21', a number of teeth in the same proportion. When the segment 9 has arrived at the end of its stroke, it will strike rib 15, pushing the same backward, until the same engages notch 27. Arms 14, and their connecting rib 16 will consequently be lifted during the movement of part 15, so that rib 16 striking against arm 60 of rack 37 will cause the same to swing back releasing stop 43. The action of the spring motor then pulls the carriage toward the left, until stop 44 'stri kes against the tooth 42 formerly engaged with 43. This first half-stroke of the carriage is such that the wheel 21 formerly in mesh.

with 20 has been displaced enough to have the corresponding hub 21' opposite to wheel 20, so that this is now free to move without causing any movement in the counting wheels. Upon releasing the lever 3, segcause .thereturn forward of rack 37: thus freeing stop 44, the tooth 42 of the rack en gaged by the same passing through the free space 45. The carriage isjthen free to complete its stroke, until the next tooth 42 of the rack will be in the way of stop 43. At this stage the carriage is stopped, and a new wheel 21 is-in front of wheel 20 for the next numeral to be inserted. By depressing the -lever 6, corresponding to the numeral 0, its end 17 strikes against 16 causing the back movement of 15, and operating the rack in the manner described, the carriage being moved one space to the left. During this backward movement of part 15, lever 24 will .not fall on account of its weight, inasmuch crates against arm-60, causing the swinging of the rack 37 and the motion of the car. riage also of one space to the left. 30

When

the carriage has to be moved for more than one space, it being necessary to start the insertion of a new addendum from a given colto'move toward the left until stop 53 strikes against the rod 54 which is depressed. Upon releasing this lever and stops 43, 44 are again lowered by the action of spring 16 so that the carriage will not move farther. The

. insertion of the new addendum is then started and completed.

To avoid the complication of an auxiliary a shaft and gears, used in many adding mechanlsms for causing the motion of the next higher wheel of onespace when the number 1 ten is passed in any given wheel, I have de- 50- vised a novel and simple arrangement for the relative motion of the different counting wheels, which I shall now describe.

Each hub 21" is provided with a finger 62, which in its rotation will clear the wheel 20 which might be in the corresponding gap '61; said gap 61 being sufficiently wide for the passage of both wheel 20 and finger 62 at the same time. Int-o each gap 61, at the rear of the hubs 21', is located a lever 63 loosely mounted on a fulcrum 64. Said lever is held in the position shown in the drawings (Fig. 1) by the action of a spring 65, and is provided with a projection 66, coming out of an opening 67 provided at the rear part of the carriage. Arm 68 of lever against which is pressing spring 65, is of such a shape that said spring can hold the lever in 1). A pawl 69, engaging the toothed wheel 21 on the left of each lever 63, is loosely mounted on pin 70, attached to said lever, and has two arms; one 69 engages the toothed wheel, and the other, 69", is bent downward, and is used to disengage arm 69" by operating a rod 71 at the rear, as will be at a later stagedescribed. The carriage is provided with windows 7 2, through which the different numbers appear; and the position of finger 62 shown in the drawing corresponds to the figure 9 appearing through the corresponding window 72. Upon the counting wheel being rotated, finger 62 will push lever 63 in its lowered position, where it will be held. by spring arm 69 of pawl 69 will have thus engaged another tooth of the next higher counting wheel. I

73 is an inclined plane attached to the back of the case 1, against which projections 66 of the levers 63 which happen to be in the lowered position strike when the carriage is returned to its starting position. The action of said inclined plane is to return such levers to the raised position, pawls 69 causing the corresponding wheels 21 to advance one space forward, and thus effecting the addition of ten units due to the next wheel to the right having passed the zero point and having at that time lowered the corresponding lever 63.

A spring 7 3', or any other suitable means, is used to exert a braking action against any undue motion of the counting wheels (Fig. 1).

71 is a C shaped rod or yoke having its fulcrum in 74-, operated by a lever 75, normally held by a spring 7 6 against a stop 77 (Figs. 1 and 2). By swinging said lever forward, rod 71 discngages all the pawls 69; this is done in two instances. \Vhcn it is desired to correct the reading of one of the counting wheels, the same is revolved by hand through its corresponding window 72;

if it should happen in so doing to cause the lowering of the corresponding lever 63, before raising the same by means of the projection 66, the rod 71 is pushed against the pawls 69 by means of lever the lever which has been lowered is raised, lever 7:) released, and all the pawls 69 will, fall back in the same place occupied before (Figs. 1 and 2). Lever 75 is also used when it is necessary to return all the countinp wheels to the 0 mark. To this efi'ect shaft 22 is made longitudinally movable by means (if a button 78, against the action of a coil spring 7 9; said spring has one end fixed to a point 80 of the case, and also opposes the circular motion of shaft 22 (Fig. 5). Said shaft 22 is provided with projections 81, which normally do not interfere with the motion of the counting wheels, these being provided with chambers or housings 82 accommodating said projections; but when shaft 22 is pulled to the right, said projections 81 will engage noses 83 of which there is one in each counting wheel, and drive said counting wheels to the 0 mark upon the rotation of shaft 22. To do this, pawls 69 are previously raised and disengaged from the counting wheels, by means of lever 75, in the manner explained. Shaft 22 is kept in its normal po-- sition by means of a pin 84 engaging a hole in the side of the case 1.

The machine is fitted with a device for printing the different addenda on a strip of paper, which consists of a printing Wheel, a paper feed, and an inking ribbon.

On the portion of shaft 19 projecting outside of case l, is mounted a pinion 85, in constant mesh with a geared segment 80 (Figs. 2 and 4). 87 is a spring opposing the mot on of said segment and pinion due to levers 3. 88 is a stop acting against stop pin 89 to stop the backward motion of shaft 19 due to spring 87. Toward the front of the machine a pinion 90, similar to pinion 85, is mounted on a shaft 91, in mesh with segment 80; said segment 80 is free to swing around its fulcrum 92. On shaft 91 is mounted a sleeve 93, having at one end a toothed Wheel 94, and at the other a printing wheel 95 carrying the types of numerals O to 9 A spring 90, or any other suitable means establishes an elastic connection bctween shaft 91 and sleeve 93, so that shaft '91 drives sleeve 93, but when this should be stopped, shaft 91 can continue its motion until a pin 97 strikes the wall of a transverse opening 98 provided in sleeve 93. The numeral 0 is normally toward the rear of the machine.

99 is the hammer, connected by means of screws'lOO or otherwise, to part 15 (Fig. 6).

101 is a bracket attached to the side of the case, hearing guide rolls 102, 103, 10 1,

for the inking ribbon 105. Roll 104 is fitted with a toothed wheel 100, the backward motion of which is prevented by a spring 107.

108 is an inking drum for keeping the inking ribbon in the proper condition (Fig. 3).

means hammer 99 and inking ribbon 105. Roll 117 is mounted on a sleeve 119, loosely revolving around guide rod 112, and provided at its inner end, with a face toothed wheel 120. A pawl 121 is pivoted on bridge 109, and forced outward by a spring 122. If box 113 is pulled toward case 1, and against pawl 121, this is forced inward, causing face toothed wheel 120 which it engages, to re volvc, driving roll 117, and feeding the paper strip for a space between addenda (Figs. 2, 4). Box 113 is movable longitudinally in order to print the numerals in the different columns, and is driven in this motion by carriage 23. To this effect, carriage 23 is fitted with a toothed rack 123, in mesh with a gear 124 revolving on a stud 125 attached to the case. To said gear is attached a pinion 126, driving a rack 127, connected in 128 to box 113. In this manner, the suc ccssive steps in the motion of carriage 23 are transmitted in a reduced length to box 113, a new space being offered for the print ing of a numeral at each step (Fig. 8).

The printing mechanism operates as follows: Upon one of the levers 3 being depressed, while the corresponding figure is added to the counting wheel 21 in mesh with 20, the motion of drum 18 is also transn'iitted-by pinion 85 to segment 80 and to pin ion 90. This causes printing wheel 95 to rotate presenting the numeral corresponding to the depressed lever to the action of the han'nuer 99, 'When rib 15 is pushed back ward, at the end of the stroke of the lever, hammer 99, carried thereby, will strike against printingwheel 95; the inking rib bon and the strip of paper being in between. the numeral will remain printed on the latter. To insure a clear printing, hammer 90 has a-pawl 129 which will engage toothed wheel 94. thus locking the printing wheel in the right position, at the end of the stroke.

Upon releasing the lever 3, the hammer 99 and the printing wheel 95 will return to their former positions, and box 113 will move one space to the left. Hammer 99 is also provided with a spring 130, engaging toothed wheel 106, and driving the same one space upon the return stroke of the hammer. Said return stroke of the hammer is effected as stated by the weight arm 14, which controls part 15,to which hammer 99 is attached; and it is of course understood that said arm 14 will have to be made suifieiently heavy to perform the return motion of the hammer, at the'same time driving toothed wheel 106. In this way roll 10 i is revolved at every insertion, providing a silnm ple and efficient feed for the inking ribbon. When an addendum has been totally inserted, the eariage 23 is returned to its initial point, to start the insertion of a new addendum. This motion is followed by box lib.

upon the releasing of said 113, which will thus be brought against pawl 121; this will cause wheel 120 to rotate of one space, thus feeding the strip of paper accordingly, and offering a new space to the action of the printing wheel.

From the foregoing it will be seen that I provide a novel disposition for imparting the motion to the different counting Wheels, simple in design and inexpensive to manufacture; also an improved way of imparting a partial rota ,ion to the wheels of higher denomination, upon the completion of one rotation of the next wheels of smaller denominatioi'i. It will also be noted that I provide a most simple disposition for driving a printing wheel instead of the type levers usually adopted in this lrind of machines.

It is obvious that while the dillerent numbers of teeth indicated oy me for the various moving parts are those that most conveniently answer the purpose of my machine, they can be varied provided the relative proportions are maintained; it is also obvious that in the printing arrangement the record. strip "can be made station ary and the printing wheel may be made longitudinally movable. These and other changes can be made in the specific details of construction of machine, without departin" from tie spirit oi? my invention; there. at I do not wish to be restricted to those saown and described.
